Needing bulkhead pinout from a 96 XJ

Have a buddy who is swapping a 4.0 from a 96 XJ into his 95 YJ that had a 2.5, we are having some trouble with the wiring and are needing help with getting diagrams for the bulkheads on both to see what pins need to be swapped. Any help would be great, thanks!

Post #1 - welcome to the forum!

So you’re using the XJ computer and stuff? Was the 96 XJ OBD2? I can’t recall

The easiest to me (cuz it’s what I did) is to use YJ sensors on the motor. Then there’s I think only one might’ve been two wires in the 60-pin connector to move, plus add two injector wires and mine ran first try. You just need a six cyl 4.0 ecm which plugs right in. I happened to have a ‘91 4.0 parts rig and most of a 1991 2.5 YJ to harvest from but you mostly don’t need that.

There are links and stuff here: https://www.jeepforum.com/forum/f12/m...topics/3353321 but in my case I used a 97 Cherokee motor in an ‘89 with a 1991 YJ harness and computer. Other than a little wiring color weirdness the ‘91-‘95 harnesses are essentially the same so the process is identical

That thread is rambling and long but there’s good info in there as I attempted to document and include resources for future use- I just never re-wrote it to clean it up.

IIRC the 2.5 sensors have the same plug shapes as the 4.0. I “think” the XJ throttle body will run off the YJ OBD1 harness and ecu but the plug is different. I think I used the YJ throttle body because I swapped the manifold to the YJ manifold so why not?

(I believe @Luuca has also done this swap)

Here is a link to the 95 FSM for YJ: https://www.dropbox.com/s/ret5kdafmr...anual.pdf?dl=0

Ill see if I have one for a 96 XJ 4.0

will let you know tomorrow.

EDIT:

I was looking through he FSM I linked and it has the diagrams for both 95 XJ and YJ. That may help if they are identical./.. 96 could be as well. didn't look. Up to you..

The FSM pinout page for both shows the pin and the circuit, is the only way to figure out the actual description of each pin to chase down every one individually?

I believe he may be going with your recommendation of getting a PCM from a 95 4.0 and using all the 95 2.5 sensors and harness, because yes the 96 is obd2.
